A five-level PE-model was applied to simulate the formation of sub-synoptic systems using real data of rainfall amount and geopotentials. Experiment indicates that due to release of latent heat through condensation process in the numerical model a convergence zone and a sub-synoptic vortex develops in the precipitation region. The low level jet stream with scale about 500 km is located along the south side of heavy rain area. The wind profile, vertical circulation and location of low level jet reletive to the...

A five-level PE-model was applied to simulate the formation of sub-synoptic systems using real data of rainfall amount and geopotentials. Experiment indicates that due to release of latent heat through condensation process in the numerical model a convergence zone and a sub-synoptic vortex develops in the precipitation region. The low level jet stream with scale about 500 km is located along the south side of heavy rain area. The wind profile, vertical circulation and location of low level jet reletive to the heavy rain area are in agreement with average structures of Mei-Yu front. The dry numerical model can not give similary results.

本文对两个典型暴雨个例的平均结构、大尺度热量、湿度和动量的平衡进行了考察。一个重要的结果是无辐散层略低于500毫巴,其下面为辐合,上面为辐散。大尺度上升运动在整个对流层里,无辐散层处有一个极大值。此结构不同于强烈对流天气的结构。 由于次网格尺度的对流使总热量(热量和湿度)向上输送,因此对流层下部有总热量的净减而上部有净增;500毫巴以下有湿度的水平辐合,以上有水平辐散。对流层上半部的水汽来源于下部。在暴雨区上空由于凝结而在深厚气层中为视水汽汇(apparent sinks of moisture)。对流层中上部有动量向下输送,最大通量约为3—5达因·厘米~(-2)。次网格尺度的动能对能量平衡有很大贡献。

On this basis, the average structural parameters of various generic fractions were obtained by generally accepted Williams and Brown-Ladner equations and the average molecular structural models of these fractions were designed.The consistency between the structural parameters of combined ~1H-NMR-IR method and the Densimetric method by van Krevelen shew that the densimetric statistical method remains a simple and accessible method for structural analysis, but more information can be got from ~1H-NMR -IR method.
